AllocateGemma 4 31B-it FP8 GPU requirements
What it takes to run Gemma 4 31B-it FP8 locally: memory by quantization, the smallest GPU that fits, and the managed alternative.
Gemma 4 31B-it FP8 serves up to 262,144 tokens of context; the KV cache grows linearly toward that ceiling, so the slider below shows exactly what longer context costs in memory.
Smallest single device that fits: RTX 4090 (24 GB)
How it works
Common questions
How much VRAM does Gemma 4 31B-it FP8 need?
At 8K context: roughly 70 GB at FP16, 35 GB at 8-bit, and 19 GB at 4-bit, including KV cache and runtime overhead. Longer context adds memory linearly.
Can a single GPU run Gemma 4 31B-it FP8?
At 4-bit, yes: a RTX 4090 (24 GB) or larger handles it at 8K context. At FP16 you need a A100 (80 GB) or larger.
Does quantization hurt Gemma 4 31B-it FP8's quality?
Modern 4-bit quantization costs a small amount of quality for a 4x memory saving; 8-bit is near-lossless. Validate on your own tasks before production.
What license is Gemma 4 31B-it FP8 under?
Apache 2.0. Permissive: run it, fine-tune it, and own the result.
Is there an alternative to buying GPUs for Gemma 4 31B-it FP8?
Yes: managed inference. Allocate serves Gemma 4 31B-it FP8 token-metered from $0.39 per million input tokens at provider list price, plus the 7% transaction fee. Idle time costs nothing.
